Facebook is adding a new Send button to its popular social networking service. The button is designed to replicate the functionality of "E-mail to a friend" options popular on some websites, and is meant to allow links or pages to be shared among groups of friends on the service. Uses of the button count towards a page's overall number of Likes.
The button is being launched across more than 50 sites, including Orbitz, Last.fm, the Wall Street Journal, and 1-800-Flowers. Code for the button is also publically available through the developer's network.
